Point.Y 属性

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

获取或设置此 Y 的 Point 坐标值。

public:
 property double Y { double get(); void set(double value); };

public double Y { get; set; }

member this.Y : double with get, set

Public Property Y As Double

属性值

Double

此 Y 结构的 Point 坐标值。 默认值为 0。

示例

以下示例演示如何检查两个 Point 结构是否不相等。 它还说明了在声明结构时以及如何在声明结构后向 Point 结构赋值。

// Checks if two Points are equal using the overloaded inequality operator.
private Boolean pointInequalityExample()
{
    // Checks if two Points are not equal using the overloaded inequality operator.

    // Declaring point1 and initializing x,y values
    Point point1 = new Point(10, 5);

    // Declaring point2 without initializing x,y values
    Point point2 = new Point();

    // Boolean to hold the result of the comparison
    Boolean areNotEqual;

    // assigning values to point2
    point2.X = 15;
    point2.Y = 40;

    // Compare Point structures for equality.
    // areNotEqual is True
    areNotEqual = (point1 != point2);

    return areNotEqual;
}

' Checks if two Points are equal using the overloaded inequality operator.
Private Function pointInequalityExample() As Boolean
    ' Checks if two Points are not equal using the overloaded inequality operator.

    ' Declaring point1 and initializing x,y values
    Dim point1 As New Point(10, 5)

    ' Declaring point2 without initializing x,y values
    Dim point2 As New Point()

    ' Boolean to hold the result of the comparison
    Dim areNotEqual As Boolean

    ' assigning values to point2
    point2.X = 15
    point2.Y = 40

    ' Compare Point structures for equality.
    ' areNotEqual is True
    areNotEqual = (point1 <> point2)

    Return areNotEqual

End Function
